Area of circle with 18 inch diameter = pi*(18/2)2 = 81*pi sq inches
Area of circle with 9.6 inch diameter = pi*(9.6/2)2 = 23.04*pi sq inches
Difference = (81 - 23.04)*pi = 182.09 sq inches.
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
The area of a 18-inch diameter circle is: 254.5 square inches.
A cylinder has a diameter of 18 inches and a height of 25 inches has a total surface area of approximately 1,922.65 square inches.
Area = pi*9*9 square inches
Area of circular pan: pi*9 squared = 254.469 square inches Area of square pan: 18*18 = 324 square inches which has the greater area
The 18" refers to the width (diameter) of the pizza.
Using 3.14 as Pi the area of circle is: 254.34
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
about one or two inches wide
Diameter = twice the radius = 2 x 18 = 36 inches.
Area of the circle: pi*92 = 254.469 square inches to 3 decimal places
The circumference of a circle that has a diameter of 18 inches is about 56.55 inches. (C = d x Pi).
